GPS Question - Vibrant Q&A, Help & Troubleshooting

So I've got a Vibrant running Stock 2.1 with the JI6 OTA update. For some reason, like most others, the gps has never worked nor is it working now. I've done the quick fix for stock users by setting my phone to MS based, switched it to supl.google.com with 7276 for the port and can now see about 9-10 gps's at any given time, (and to add the compass works amazingly) the problem is that even though I see these satellites I never get an official lock. I've done gps test and even the performance test through *#3214789650# and I cannot get an official lock. I've since switched to and from these settings and the original settings with no change, and when it is set on the original settings I only see 1-4 satellites and never get a lock. Anyone have any suggestions or am I just boned till 2.2 froyo and pray that when that's officially released the gps will officially be fixed? Thanks if you can help ^_^

I recently installed the latest bionix ROM and the GPS was pretty much fixed. Locked on in seconds and was not as wonky as it was before.
I suggest you give it a try.

There seems to be a minority, myself included, for which the JI6 hasn't improved GPS performance. I've tried falling back to JFD and upgrading to the stock JI6, as well as other ROMs, including Bionix 1.9.1. No joy.

GPS was solid but now? )-:

So a little about my phone. I am running a custom ROM Fusion 1.1 with a custom Kernel from Team Whiskey Core V3 2.1 also have OCLF. My phone right after flashing the new ROM seemed to lock on quickly to several Sats 5 plus every time. But for no reason and with no adjustments to the default settings I now have a very hard time locking on to any Sats. Takes 10 plus minutes and only can get a few to lock.
So the only things I have changed on my phone recently is trying a few different Kernels. Would this even effect the GPS sat locks at all? I would think not but??
Anyone have anything new that I have yet to read about that they have tried that seems to make the GPS better?
My phone's GPS might just suck who knows.
Thanks in advance!
Did you try digital toddys fix?

Yea I did.. Just went outside and switched to Cold then delete GPS data ran fix for 10 minutes and got a lock on 4 sats. Switched back to Hot and didn't seem to help much.
You did the reboots and everything?
Odd man, if that didn't work I am at a loss. Hopefully others can chime in for you.
I would think the ROM is what affects GPS signal the most. I was running Bionix 1.9 with KK kernel and the GPS was money. Now running Obsidian V1 (didn't switch to V2 because I read people were having GPS issues on it), and GPS still works great. In fact, when using Car Home, it shows the exact street address I am at.

from what i understand, yes a different kernel can affect gps because the kernel contains the drivers. it is my understanding that this is why the 2.2 roms have working gps now: an 'official' kernel was leaked and the gps drivers were pulled from it. however the rom will also affect gps. for example, i was running bionix 1.9.1 and gps was great, flashed bionix final and gps went to ****, flashed fusion 1.2 and gps was working again.

[Q] GPS signal lost on multiple roms

So I've done a lot of searching and haven't really found anything definitive. I've found that with some roms I'll lose GPS signal after a certain amount of time (say 10-30 minutes) and have to turn GPS off and back on or reboot the phone. I saw something about flashing a different radio may make a difference. Kinda just wanted to see other peoples thoughts on the issue or if maybe there is something else I can do before I go flashing a different radio.
Currently running CELB 4.1 and baseband 2.42.01.04.27 and I have the issue.. I've had it with most of Tazz's roms as well. KaosFroyo is the only one Ive used that I've never seen the issue with, but I'm really diggin CELB right now and this is the ONLY issue I've got with it.
Have you tried GPS status in the market? I know it will help you lock in a signal, so it would make sense that it would also help keep your GPS locked in.

I have now.. I did the reset and download options in the program. Too bad this isn't something I can quickly test. I'll report back with the results. Thanks!
I have noticed this as well. Last time it happened to me it was 4:30 in the morning, and the "GPS lost" message came up about 180 seconds before I had to make two freeway changes in an area I'd never been before. (CELB 3.9 and same radio as your case). Fortunately for me I had reviewed the route, so I more or less knew what to do.
If I recall correctly, it has always happened after the Nav app had been running for a fair bit of time - at least 30 minutes or more.
However, I don't know if it is something about the root ROMs or not - I started using rooted ROMs back in March or so, so I really don't have a tremendous operating baseline on stock 2.1 ROMs to compare it to. Maybe it is a problem there, too!
If I recall correctly, the last time it happened, I just pulled up GPS Status and asked it reload the aGPS state (without exiting the Nav app), and the Nav app seemed to gracefully recover.
Annoying? Yeah. I don't know what can be done about it, though - like the "undead calls" problem, it happens so infrequently that it is hard to know whether or not a ROM change actually fixes the problem.

I had the same problem with every 2.2 rom I used GPS with. I decided to go back to 2.1 because I have been needing GPS alot more often lately but I havent tested it out since I made the switch. I'll try it out today and report the results tonight.
This same thing seemed to happen on the 2.1, CyanogenMod 5 based ELB by Conap as well. If it is happening with all of the 2.2 ROMs, I wonder if it's just a CyanogenMod issue?
See http://forum.xda-developers.com/showthread.php?p=6812308#post6812308 (this was not the only person reporting it, if you search that thread.)
I really don't think it's ALL 2.2 CM roms though. I've gone on 7 hour car trips with Kaos Froyo without a single drop.. to and from. I've seen another theory somewhere around here about it being certain hardware revisions that act this way with certain software builds. At lease we've got a thread dedicated to this issue now.. maybe we can get something figured out.
Still don't know if the GPS status program helps.. I left navigation turned on for a bit sitting in my house and it stayed connected for the half an hour I left it, just don't think that's gonna be an accurate test with not moving around and all. If it doesn't work I will try a different radio.. I saw somewhere one guy had good luck with a specific older version radio. If that's what it comes down to I'll try.
I have been having issues with the GPS working on both of my phones while using 2.2 roms. I switched to 2.1 a few days ago and I used the GPS on my way to work this morning and didnt have any issues. I also had to flash Senseable a couple of months ago while on a road trip because I was tired of loosing the GPS signal every half hour. It may be a CM thing.
Im having the same issues as well. Haven't found a fix yet..
I've had this issue, after I flashed KaosFroyo(v36), and XTR(4 i think). I recently unrooted using Flashback21 v1 and flashed with the radio included. I have gone back to xtr 5 now and have had no lost gps in over a week. Don't have a clue as to why. hope it helps someone.

give us another update. is the gps problem still fixed for you? Thanks!
I have flashed the radio directly with the verizon zip file that is around and I still get inconsistent results But it always drops a signal eventually in about a 1/2 hour

I've seen it on several ROM's as well. From what i've messed with, it doesn't seem to be dependent on the autokiller memory preset, radio firmware, or amount of overclocking i'm doing. It doesn't seem to be dependent on how many programs are running either. I usually have nav and pandora running while i'm in the car, and sooner or later, the gps poops out.
I feel like it seems to happen less, now that i'm back to using the on-demand governor. but that could just be in my head.
I've had to go back to a 2.1 rom because of it. Its very annoying when the goa signal gets lost right before the exit ramp.

Im thinking of going back to a 2.1 rom as well...
I have also seen the same results on any 2.2 or higher rom. I have since returned to XTRRom 5.0 and have not had a single problem with GPS on any of my jogging runs. I definitely think it is a CM thing. At least on my phone.
Using kaosfroyo v39 and I flashed that sprint phone radio on my eris and haven't had any gps issues. In fact, just the opposite. Mine would lock up before the v39 and the radio flash
I flashed that radio as well and today not one issue at all. Will test more tomorrow
I'm using the 2.42.02.10.29 sprint radio and still seeing it drop out.

Today I even flashed back to the July 2010 version (2.42.01.04.27). the gps dropped out almost every 5 minutes while i was driving around. that's the worst i've seen. So i flashed back to the 2.42.02.10.29 sprint radio again. I haven't seen very good navigation performance on the v1.1 gingershedbread overall, actually. my position on the gps nav doesn't update very often, although it seemed like the voice instructions were still pretty well timed as usual.

GPS help!

Hey all,
Just wondering what setup everyone has that their gps works fine (i.e. gps lock within 10 seconds). My GPS takes FOREVER to lock on, and most of the time its not even worth waiting for. I am running CM7 build 17, so no nightly builds, and i have the glitch 11 kernel running and the EC09 radio. Any help is appreciated, cause this is my one caveat with this phone. Thanks
Ninja edit: totally didnt see this guide, http://forum.xda-developers.com/showthread.php?t=1239090 when i was looking around...still comment are useful!
My gps works great as long as it can see a cell tower to get it started. Once I'm off grid, it can be painfully slow or not lock at all.
Samsung phones generally aren't the greatest when it comes to gps.
I voided my warranty and your mum.
are you running a custom rom? i honestly think EC09 is the problem..
powerwashed ed05 rom, pbj kernal, ec09 radio. Gps works flawless!

Same thing on all ROMs including stock for me. It's fine until I lose cell signal, then it's crap.

[Q] GPS Broken Broken

Hello well not sure but I think my GPS is "broken broken" like maybe something hardware related but just wanna to check with you guys first instead of doing anything drastic.
I think I first noticed when i was on a build of trigger(cm based) that the GPS kept searching for location and unscessfully tried the CM7 GPS script. I then just decided to Odin back to stock and getting the same results GPS wise. I also tried Nandroiding back to a ROM that knew GPS worked when i use to use it(toxic w7 clone) but still no luck. Also worth noting that while on Stock Odin I tried some different Market based GPS fixes(GPS Restore GPS Aids).
Any help would be appreicated thx
some people have working gps, some dont. mine kind of works but it takes forever to lock.

Did your GPS work in the past?
I used a 2.2 build of Trigger a little bit back, and it did the same thing to my phone. I have a "fixed" hardware GPS antenna (since I did the FFC mod, fixing the GPS at the same time was a piece of cake), so when I suddenly couldn't get any GPS signal, I knew something was most definitely up. I tried the sgps "fixes" to no avail.
Eventually I flashed CM7 (since gps wasn't working either way, at that point), then Odin'd to stock, then flashed Bionix 1.3.1, and suddenly at some point it fixed itself. Now my GPS is back to working on CM7, as well as 2.2 roms.
So, if your GPS used to work fine, there was something software-wise which screwed it up.
Do yourself a favor and call TMobile. Tell them that your GPS doesn't work and you'd like a replacement. Do it three times and get a completely different phone for free.
The Vibrant is a POS at best.

Hmm.. i did see a post where someone said it took 5 minutes to get a lock maybe I'll try the GPS test again for longer period.

Sorry bout that I should of mention that GPS was working in the past, never tried Bionix I'll see if that does the trick.

Yeah this what I meant by drastic but probably my only real solution, wonder how that works though im pretty sure I'm paying for some replacement/warranty but that's only if they find out it is broken or defective right?
So glad i bought a Vibrant for my birthday as my 1st smartphone
Well I think I made some progress here, I Odin back to Eclair and to Bionix. GPS still wasn't working but GPS Test shows that there are some Satellites "in view" but not "in use" weird...

[Q] GPS Issues with CM7.1 (stable)

Hi,
I've been constantly having issues with the GPS on my vibrant. I got a replacement vibrant from t-mo about 3 mos ago because the GPS rarely locked on my original phone. This new phone's GPS worked fine for a while with the stock Froyo ROM. It always seemed to lock in less than 1 min. After a few weeks, the GPS stopped locking reliably for me.
I tried an update to CM7.1 and didn't see any improvement with the GPS.
So, here's my quetsion:
1. What is the best ROM for GPS usage on the vibrant?
2. Is this GPS Fix still relevant?
I'm running CM-7.1.0.1-Vibrant.
Kernel version - 2.635.12-gdf10700 [email protected] #1 (that's a mouthful).
Thank you.
If GPS needs to be absolutely 110% working, then MIUI (if you want GB) or any 2.2 ROM will suffice. As for the other GPS fix relevancy, it can be really hit or miss. On some GB ROMs it works, on others it doesn't. It's really by chance that the planets align and the powers above grant you vibrant with working GPS

I have a similar problem, I found a solution in ICS ROM.
When you turn on the phone, before it finds a network, you need to run any diagnostic applications of GPS, for example GPSLB TEST NB and immediately start the GET POSITION.
You will find that it finds satellites at once. Turn off the software.
you have GPS working until the next reboot...
The vibrant has always had gps issues. Theres a fix somewhere i cant remember where. Havent had a vibrant in awhile
